How should the number one anti-cancer vegetable, sweet potato, be eaten?
Cancer cells originate from human epithelial cells, and sweet potatoes are rich in starch, carotene, and more than 10 trace elements such as potassium and iron. These components can protect the structural integrity of human epithelial cells, inhibit viral activity, block the production of nitrosamines in the gastrointestinal tract, and eliminate toxic effects caused by mercury, cadmium, arsenic, and other substances from food or the environment, thereby interrupting the carcinogenic process of toxic metals. Sweet potatoes are called by experts the most balanced health food. The unique dehydroepiandrosterone (DHEA) in sweet potatoes is a steroid hormone similar to androgen, secreted by the adrenal glands, which can both prevent cancer and promote longevity.
What should you pay attention to when eating sweet potatoes?
1. It is best to eat them at noon
In terms of the time of day, it is best to eat sweet potatoes at noon because after eating them, it takes 4-5 hours for the body to absorb them. At the same time, the afternoon sunlight can help promote calcium absorption. Eating sweet potatoes at night means the sugar content is high, and the body may not be able to absorb it all at once, which can easily cause bloating.
2. Do not eat them with sweets
Sweet potatoes are already sweet, and eating them with other sweets can increase the likelihood of gastroesophageal reflux.
3. It is not advisable to eat sweet potatoes on an empty stomach
Sweet potatoes also contain an oxidase that produces a large amount of carbon dioxide gas in the gastrointestinal tract, which can easily cause symptoms like bloating and belching.
4. Do not eat the skin of baked sweet potatoes
Sweet potatoes contaminated with black spot disease are difficult to identify after baking, so do not eat sweet potatoes with black spots or those that are scorched, as they may cause poisoning. Also, although many roasted sweet potatoes on the streets now use ovens, many are still baked with coal. When coal burns, it produces a large amount of harmful substances such as sulfur dioxide, which is detrimental to health if consumed in excess.
Precautions for Eating Sweet Potatoes
1. Patients with diarrhea and diabetics should not eat sweet potatoes. People with stomach problems should not eat too many to avoid bloating.
2. Sweet potatoes should not be eaten with persimmons. Sweet potatoes and persimmons should not be consumed within a short period of time. If large quantities are eaten, there should be an interval of at least five hours. If eaten together, the sugar in sweet potatoes will ferment in the stomach, increasing gastric acid secretion. This will react with the tannins and pectin in persimmons to form a precipitate, creating hard lumps. In severe cases with large quantities, this can cause gastrointestinal bleeding or stomach ulcers. If you feel discomfort in your stomach, be sure to go to the hospital for a gastroscopy to check for gastric bleeding or a stomach ulcer.
